Next time you make a trip to the grocery store, it might be a good idea to purchase a new set of tupperware to be used specifically for your aquarium. These plastic containers are great for everyday use, as they can serve as portable fragging stations, a place to dissolve frozen food, or just a tool to organize smaller supplies. The thing you have to worry about with using plastic kitchenware is your spouse’s response. Don’t get caught taking the food containers from the kitchen cabinets, and really don’t get caught putting food items back into them after you’ve spent a day cutting corals into them. If you do decide to buy your own plastic containers, there’s really nothing specific you need. Virtually any container will do.
